Vauxhall Insignia P0673 Compression Sensing Glow Plug

[@OneAuto]

Picoscope featured this video on their July 2017 newsletter. mailchi.mp/picoauto.com/july-2017-picoscope-news-guided-tests-case-study-and-videos

[@TrueBlueEG8]

What a good video, with an excellent explanation and lots of detail. I am 20 years a mechanic and I am still learning every day. Having a good teacher like you is such a benefit to younger lads. You keep up what you do and I am sure this channel will grow and grow. I see you too have also evolved into a human torque wrench :)

[@OneAuto]

Thanks I appreciate that. I am 31 years in the trade and still learn every day! Always remember the common sense torque wrench was invented long before actual torque wrench :)

[@wysetech2000]

With a Vauxhall the light should say "trade in vehicle soon" Well done, Rob.

[@train4905]

An absolutely butifull,diagnosis sir. I really loved the use of all the test gear.absolutely brill bud.

[@wyattoneable]

Man that PICO is one fantastic tool. One must attain the skill to use and understand it, but you got that nailed. Nice fix Rob.

[@OneAuto]

Cheers Wyatt, it does so much more than I know how to use. I'm using it more now I have a decent laptop. The old one took an hour to boot up :)

[@zedman442]

Thanks for sharing. Like you say you need to be 100% when diagnosing expensive replacement parts. Most would just buy it and replace the faulty part and most the time it will fix the problem. That is what separates a professional like you to the rest because you can follow it through to the end, the nice kit does help though!

[@OneAuto]

Thanks very much. I like to prove as best I can before playing swaptronics :)

[@labradormcgraw2409]

Nice work. I've never seen a how-to glow plug video before, so this was really interesting. Thanks.

[@OneAuto]

Glad you liked it. Cheers 🍻

[@stuzman52]

Nice diagnostics and work Rob and the Pico did a great job for you in finding the issue! :)

[@OneAuto]

Thanks Terry, it sure did!

[@CharlesK441]

Awesome! I've been told I need to change all plugs even though only one at fault. Too expensive for me right now

[@sandyande]

thanks for video Rob great diagnostic procedure explained, do u know if u can get pressure readings on the scan tool from these glow plugs cheers sandy

[@OneAuto]

Hi Sandy, yes apparently you can but I forgot to look. I'll check it out next one I have in.

[@denny9931]

The 2009 did not have the pressure sensing glow plugs. It was introduced with ecoflex models, later in the series the 2.0 CDTI might have 0, 2 or 4 pressure sensing glow plugs. They can be identified by amount of contacts at the connector. So check which ones are needed before ordering new ones.

[@SteveRobReviews]

Nice one Rob, never knew they were compressor sensors on them. And just one little grunt and bob's your uncle. Smashing mate.

[@OneAuto]

Cheers Steve, I've just been told the setting was a Nano Grunt!

[@simonparkinson1053]

Just diagnosed the ex's Zafira C with P0672, had the spanner light a day after the service, the dealer replaced the glow plug under warranty. A week later, spanner light again, P0674! It's going back in, just outside warranty by a day but seeing if they will replace No.4 and also No.1 and 3 as there's only 24,000 miles on it. While they don't need the glow plugs to start, they do need them for DPF regen so they can ignite fuel injected on the exhaust stroke to create the flame thrower!

[@OneAuto]

Good luck with the claim 👍

[@LimitlessAdventure]

Thanks so much for this video.I just got one of my glow plug changed from local garage who had diagnostic kit and it all works..no more errors. Thanks

[@claudiuberta5688]

Hi Andy, hope you are doing well. I recently bought an insignia and had to change the pressure sensor glow plug 2x in my case, now the car trows an cylinder 4 pressure circuit high (P03b6) and I could find any other issue as such online, would you belive is the wiring harness related? I've changed the glow plug module already. Also what would you recommend to test further, many thanks. Claudiu.

[@Exploring_beautiful_world]

What i have got is that its from left to right 1 to 4 and what i am not able to do is simply removing the cord from tje plugs is there any specific point to press while pulling the cord?

[@AdrianKingsleyHughes]

Yikes! After watching that video you linked to on how those compressions-sensing glow plugs work, man, that's a lot of stuff to go wrong! Great video!

[@OneAuto]

I know crazy how complicated things are becoming:)

[@LMAutoRepairs]

Great video and repair. Thank you for sharing!

[@OneAuto]

Thanks Luis 👍

[@shaunsautorepairs5410]

Nice one rob...had a 12 plate insignia in today with the same fault but on number 1..was wondering what the ohm value was now i know...great stuff

[@Badgertronix]

those plugs look unnecessarily fancy. You didn't snap it off in the head so great job! 11nm is a tickle according to Brussels

[@OneAuto]

I know, some have them and others have standard ones. Yep a 'Euro Grunt'

[@padraiggalvin2807]

Good video. I never thought there were 3 contacts on that one plug before. Interesting

[@johningram9017]

Hi , does the lead just pull off the glow plug please ? i have the same as this but my lead wont pull off .

[@OneAuto]

Yes just pull off

[@jaredhind]

@9:16 that connector came straight off. Mine are super stiff, is there anything I need to press in on these connectors before I can pull them off?

[@OneAuto]

Jared Hind No not on that type but they can be tight

[@paulmayou370]

Great Video Rob i`d like to know were you buy torque wrists from not seen any for sale

[@OneAuto]

Eric O has them in his Amazon store :)

[@paulmayou370]

lol ordered one now cheers Rob lol

[@giantkiller643a]

considering now i know how to change the sensor glowplugs on my insignia i appreciate video's like this many thx for sharing them m8 thx

[@Mark-gf7yw]

This glow plug heater circuit was obviously faulty and needed replacing, but there was a TSB relating to issue's with the PSG's on these engines sometime in 2012 , basicly Vauxhalls answer to these PSG's not being fit for purpose was to carry out a software update where the codes for pressure sensor circuit faults will be logged but no longer activate the MIL. So the very expensive pressure sensing part of these glow plugs is actually useless.

[@cardude5323]

MARK FINN a lot of the new common rails don't even need the bloody things anyway. I had a 12 year old C220 with 3 dead plugs and it started first time every time no problem. Even down into the minus degrees. Apparently they are now only used for emmisions regs and to help start the car in -15c or lower which we rarely if ever see in UK. So needless to say I left them alone.

[@marchughes4731]

Can they be replaced with standard plugs? I have 3 registering pressure reading eratic but the car drives spot on with 53mpg

[@hansoloLDZ]

Why does the plug pulls 23 amps? It's 0.8 ohms so given 14.4v it should pull maximum of 18amps, right?

[@mrfinn2006]

He did not test the resistance of the meter leads first. That would need to be subtracted from the total resistance reading. The true resistance is going to be lower hence the higher current reading.

[@vdubs6068]

Great vid Rob. Your right about them not been cheap we changed a set of 4 on mk7 golf CR Tdi a couple of month ago @£65 each from TPS Cheers Jamie

[@OneAuto]

Yeh add £20 to that price then VAT to each and you've got it. Lol

[@laaribi_abdo]

Good job Rob Picoscope is a good tool for diagnostic, i think it's pico 4425 i think it's necessary to change all the glow plug because the 3 other glow plug will be dead soon and to put same grease in glow plug it's a good idea witch make the job easy next time when you remove the glow plug.

[@OneAuto]

Yes always better to replace all 4 but the customer declined. I can only do what I'm authorised to do. Thanks for watching

[@Antsummerfield83]

Hi I have a insignia 2.0 cdti 2015 140, I don’t have any Engine lights on but when I look at live data in my autel tool all 4 cylinders maximum combustion pressure shows around 4600 in the red when range says 0-100. Do you think this is a problem with all 4 glow plugs or maybe some module? Find it strange I’ve got no lights on the dash ect.., thank you

[@OneAuto]

More than likely the scan tool interpreting the data wrong. Like you say if the car had a problem you would have fault codes

[@estaban3248]

Hello Rob, due to necessity, namely having to replace a couple of glow plugs, I happened upon your post on how to do this, it was I might add supperb. I know this job has lots of pit falls, can you confirm for me is there at any point you might need to remove the turbo to carry out this job, for me this seems a bit extreme, my car is a 14 plate insignia elite.

[@OneAuto]

No turbo removal needed

[@estaban3248]

@@OneAuto thanks for getting back to me Rob. I thought as much, I live in reading but would be happy to bring my car to you for all it's needs as I hate having smoke blown up my chuff!!. Thanks again Rob will be in touch 👍

[@simonrawle7885]

a good video rob . you will have saved someone money . and the Insignia is one of my favorite cars

[@OneAuto]

Cheers Simon

[@steveguest8028]

Great video Rob,glow plugs with pressure sensors built in...whatever next lol

[@andymath1523]

Had Service Vehicle Soon constantly coming up also judder at 2000 rpm plus power loss read codes was these pressure sense glow plugs new one's over £100 each S/H £60 FFS . Got cheap 3 litre ultrasonic cleaner £40 of Amazon some cleaning stuff from work 30 min in cleaner lots of black filth oozing out between plug tip n body , back car now fault's gone no judder and power back

[@AKMCars]

I got error on all 4...can be all at the same time!??? Car starr very hard or with starting spray only! Same car as in the video

[@OneAuto]

AlexandruAlex Check that you have power coming out of the control relay near the battery as in the video. This controls all 4

[@AKMCars]

@@OneAuto great respevt for your response i will take your video at Opel Romania again tomorrow and shove it in their faces, fking amatours... :) I paid them good cash and they ask me to replace all 4 without even checking them like you! Just cus they sau all 4 glows error :). Thanks for your advice gonna check the relay power!!! Also my car have at 0 celsius like 11.9-12V...i tought i lose power on some consumer...:( New battery too 86Ah 800A Thanks again i will update you! Agai great respect and greetings from Romania! Subscribed!

[@xmochateaxofficial]

Good video, do you need cancel errors on ECU after you change glow plug or it goes on it's own?

[@OneAuto]

Domlinx Plays light should go out on its own and the fault code change to a ‘history’ code but I always clear it anyway.

[@GrahamReid34]

Nice vid Rob, E60 diesels have issues with the controller alot fairly easy to replace too.

[@OneAuto]

Thanks Graham 👍

[@-DC-]

after owning a insignia elite you do get used to constant faults appearing!

[@OneAuto]

I suppose you do Lol

[@rrplanb4030]

Vauxhall in general last 20 years.

[@rrplanb4030]

Japanese = Reliability.

[@sami_maran]

Do you use any grease on the new glowplugs?

[@OneAuto]

No sir

[@danttaylor]

Can I just fit 4 standard glow plugs to my 2.0 citizen Sri insignia 2010? not the pressure sensor ones

[@OneAuto]

No if pressure sensing ones are fitted then they have to be replaced with the same. The wiring connections are different to standard ones. The computer software will freak if pressure is not sensed.

[@danttaylor]

One Auto, sorry I had an auto correct on that last comment. And do you know at all which cylinder has the pressure sensor one? Apparently there are 3 normal ones on mine and 1 pressure sensor fitted glow plug

[@OneAuto]

Pressure sensing ones look like the ones in this video. Standard ones are thin without the bulbous part. Make sure you have the car scanned to make sure the glow plugs are setting the code first.

[@marchughes4731]

Can these be replaced with standard plugs?

[@AKMCars]

I heard you can't...the standard wont even work...:(

[@Chris_905]

excellent vid rob , thats something else ive learnt compression sencing glow plugs ! and i beleive 11Nm is probably a nano grunt !! lol

[@OneAuto]

Arr of course...Nano grunt. Its been a while since I was at college.

[@Diagnosedan]

Great video!

[@OneAuto]

Thanks Dan... somehow I knew you would 👍

[@Diagnosedan]

Ha,ha ha 😅 Just discovered your channel totday. Nice to see a specialist work on Euro cars . I'll be watching you😎

[@amothjon]

Great video as always Rob :) I to have got the "Service vehicle soon". The problem started when driving on high speed on the highway. Suddenly I got the power loos. And it went on limp home mode you can say. If I accelerated pushing the pedal slowly it worked, But as quick as I floored the pedal, the "service vehicle soon" came up and no more power. I just hooked it up to a computer and got this fault code. P0234- Engine overheated-intermittent p0674 cylinder 4 glow plug-permanent Do you think that just changing the glow plug will help.? My car is Insignia 2.0cdti 2009

[@AKMCars]

How did u fixed? And yes...that should do the job...also chdck coolant level to be sure

[@RdotK]

Hi Rob, I’ve recently just come across your channel and have been binge watching your videos due to the awesome content. I have a quick question which is what pico-scope do you use ? I’ve been looking on the pico website but don’t know which one i should buy. Appreciate any help, thanks

[@OneAuto]

Thank you for your kind words, much appreciated. I have an older model 4 channel automotive Picoscope can’t remember the model number. The best one to get is the 4425 amzn.to/2iNm8wQ

[@RdotK]

One Auto, thanks for the quick reply. It’s pricier than i was expecting lol, but hopefully I’ll have the extra pennies saved up by the time it’s back in stock. Also I’ve seen you using the Milwaukee impact in the vids. Would you say it’s as powerful as the snap on impact? My snap on gun is playing up and I’ve been toying with the idea of a Milwaukee impact but have heard mixed reviews compared to snap on.

[@OneAuto]

Take a look at Hantek automotive scopes, they are quite good for the money. I went from Snap on impact to Milwaukee.. never looked back. Takes a while to judge the extra power.

[@mrb1864]

good little vid this nice links and well done on the pico newsletter feature ...

[@ghegun]

Great video - love the channel - great to see the "half grunt" torque settings to full factory spec :)

[@OneAuto]

Thanks I appreciate it 👍

[@Krillekris]

I have a question for you as I might start making my own KZbin videos. Do you use any external mic? Or just what the camera has on it. Great video by the way :-)

[@OneAuto]

Just the built in mic Cheers

[@haywardsautomotive6156]

It's a bit ass twitchy...nice diagnosis Rob and nice torque you nailed it :D

[@OneAuto]

Thanks bud, always arse twitchy taking those things out. Cheers 🍻

[@marchughes4731]

Excellent tutorial.

[@peachy3143]

was this making the car run any differant? with it been faulty

[@OneAuto]

Stephen Peacham It did not, just the ‘service engine soon’ warning

[@peachy3143]

One Auto, thanks.. my 2010 plate 2.0 cdti 160 is idling terrible also getting diesel knock as I pull away . It doesn't sound right at all. as soon as it's well up to running temperatures it's fine and runs perfect. turn it of and restart the car and problem straight back for a few minutes ? it's driving me insane .. any ideas ? thanks Steve

[@OneAuto]

Stephen Peacham maybe an injector fault but that’s a guess. You better let the local diesel specialist take a look.

[@dzonisbrawo2]

Stephen Peacham hello, have you find out what is the problem with your car? I have the same symptoms... Thanks

[@peachy3143]

hi.. changed no1 and no3 injector and its faultless now

[@Chris_905]

i just watched the beru vid and looking at them plugs i would imagine they would only have half the life expectantcy of a standard glow plug .

[@OneAuto]

Well this was the first for this car at 100K miles so not bad

[@Chris_905]

One Auto, yea not bad then (y)

[@bodgitandleggitgarage]

I have a special setting for 15nm down I will have to show you it because you definitely did 12nm NOT 11nm

[@OneAuto]

Yes you'll have to show me... for a 15nm you must have a specially developed wrist action that I don't?

[@bodgitandleggitgarage]

One Auto, it's one of them things you've got it or you don't mate you just can't teach some things lol

[@mazdaman1286]

if one glow plug has gone the others are soon to follow, some unlucky punter is going to pick up a good bill soon...

[@OneAuto]

Yep, unfortunately true

[@nounoufriend]

True if its just glow plug fault yes , but seems excessive to change 4 pressure sensing glow plugs because of one faulty pressure sensor . You wouldn't change every single pressure sensor on car because one went faulty

[@adriankaill9413]

Nope not necessarily...replace them when they fail as they each cost £90

[@tigermoth3194]
